Kate Middleton and Prince William's baby could arrive just days before the General Election.

The Duchess of Cambridge told staff at the Brookhill Children's Centre in Woolwich on Wednesday that their baby was due "mid-to-end of April", which could mean that the second child arrives just weeks before Britain goes to the polls.

This comes after the couple confirmed they were pregnant just 10 days before the Scottish referendum. Announcing the pregnancy in September 2014, many termed the timing as "interesting".

The Independent asked: "Could this all be a plot to make their grandma happy, and keep everything in its right and proper place, kingdom-wise?"

Presumably, the Conservatives will be hoping for a boom in national pride and happiness with the status quo to make people vote Conservative.

The polls currently show the Conservatives slightly ahead on 34 per cent compared to Labour's 33 per cent.

While visiting the Woolwich centre, the Duchess spoke to mothers who have suffered with post-natal depression, and spoke to parents about the classic lack of sleep anyone with a baby endures.

"It can be hard, can't it," she said. "So often it’s about giving you the confidence to interact with your baby."

On top of George Osborne's Budget - also announced yesterday - this could well help the Tories to come out victorious. It could also encourage those of us thinking of taking a holiday at the end of April to book the time off work pronto.
